Phlox plant named ‘Barnine’

ABSTRACT

A distinct cultivar of Phlox plant named ‘Barnine’, characterized by its upright plant habit; relatively fast growth rate; dark green foliage color; attractive dark pink flowers with reddish purple throat; and excellent postproduction longevity.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar a of Phlox plant, botanically known as ‘Phlox paniculata’, and hereinafter referred to by the cultivar name Barnine.

The new Phlox is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to create new Phlox cultivars having desirable cut flower characteristics.

The new Phlox originated from a cross made by the Inventor of two proprietary Phlox seedling selections identified as code number 90.44.06.01 as the female, or seed, parent and 90.44.12.03 as the male, or pollen, parent. The cultivar Barnine was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Aalsmeer, The Netherlands, in 1994.

Asexual reproduction of the new cultivar by terminal cuttings taken at Aalsmeer, The Netherlands, has shown that the unique features of this new Phlox are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Barnine have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, and variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Barnine’. These characteristics in combination distinguish ‘Barnine’ as a new and distinct cultivar:

1. Upright plant habit.

2. Relatively fast growth rate.

3. Dark green foliage color.

4. Attractive dark pink flowers with reddish purple throat.

5. Excellent postproduction longevity.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph comprises a close-up view of a typical flowering panicle of the new Phlox. Flower colors in the photograph may appear different than the actual colors due to light reflectance.
